Valid 201200Z - 211200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Organized severe thunderstorms are not currently expected on
Saturday.

....Discussion...
A mid-level trough will amplify across the northern Plains/Upper
Midwest on Saturday with ridging across the eastern CONUS and the
Rockies. A weak surface low will accompany this trough across the
Upper Midwest with a cold front extending southwestward into
southern Nebraska/northern Kansas. South of this front, a moist
airmass will be present with moderate instability anticipated.
A MCS will likely be ongoing at the beginning of the period across
Kansas on the nose of the low-level jet. As this cluster of storms
moves east through the day, additional storms are possible in its
wake (across Oklahoma, southern Kansas and the TX/OK Panhandles)
where moderate instability and weak isentropic ascent remains. These
storms may pose a threat for isolated hail or wind gusts. However,
while this area poses the greatest threat, the overall threat for
organized storms remains low given weak (less than 20 knots)
mid-level flow and a lack of more focused ascent.
